Allow disabling/customizing of the emoji trigger (default is semicolon)

[a-scolan]

Hi,

Juste realized this issue was known and wanted to report this here : https://forum.obsidian.md/t/how-to-disable-hotkey-to-open-emojis-window/100425/8

Semicolon triggers an emoji insertion completion popover, this can be annoying as it forces use of escape key to keep typing. Allowing for customizing this trigger key or disabling would be useful.
